Are you a Samsung Galaxy S owner looking for some oh-so-cool Android 2.3.4 ROM? Good, you’re in the right place. Just in case you’re quite unsure if you should do it, let me tell you a few reasons of why you should install custom ROMs, especially CyanogenMod 7. In my opinion, CM7 is hands down the fastest and most functional ROM I have ever flashed on my SGS, plus it has many great standout features and customization options which makes it so much better than the stock ROM. About the visual elements, features and performance, you should take a look at the video below…

Convinced? Let’s proceed. The most preferred and the simplest way to install CyanogenMod on your device is via an app called ROM Manager which you can download from the Android Market. Go ahead, download the app and run it.

Note: ROM Manager requires a rooted device.

From ROM Manager, choose the first option: Flash ClockworkMod Recovery to update the app to the latest version. Select Galaxy S (MTD) > select Yes > select ClockworkMod 2.x > select OK. After this, select the Download ROM option from the main menu > select the CyanogenMod option, and then choose the latest version of CyanogenMod from the menu.

Note: When you select the latest version of CyanogenMod, check the Google Apps option. You’re going to need this in order to have the Android Market and some other Google apps which doesen’t come preinstalled in CyanogenMod.

Once the ROM is finished downloading, it asks if you would like to Backup Existing ROM and Wipe Data and Cache – I highly recomment you to do so – just to be on the safe side in case something goes wrong. If Superuser prompts for root permissions check to Remember and then Allow. The Samsung Galaxy S will now reboot into the recovery, wipe data and cache, and then install CyanogenMod. When it’s finished installing it will reboot into CyanogenMod and you’re done! You’ve successfully instaled Cyanogen Mod.

Note: If something goes wrong and your phone doesn’t work anymore as it should, do this: power off your device completely (remove battery if there is no other way). Press and hold Volume Up + Home Key and while you continue holding those buttons, press and hold power. Your phone should boot into recovery mod. From there, just select the recovery option and select the backp which you just made.
